Answer:
[7 - (-2)]2 + [-1 - 4)2 = 92 + 52 = 106
The distance is 1061/2 = 10.3 (correct to 1 decimal place).
I usually use my calculator to do square root, but you could do it by Newton's method, starting with 10.
Answer:
y=7/5x+26/5 and y=-5/7x+66/7
Step-by-step explanation:
if it's parallel, it needs to have the same slope, so the equation is y=7/5x+26/5. the perpendicular line is y=-5/7x+66/7.
I think it's A! definitely not C or D
Answer:
d)
Step-by-step explanation:
The domain are all the possible values for x. For this graph the domain will continue on forever in both the positive and negative direction, so (-∞, ∞).
The range are all possible values for y. For this graph, k affects the height of the graph. Since k affects how far up/ down you move the graph, therefore (k, ∞)
The h in the equation shows how far you move the graph to the left/right.
